SPECIFICATION forming part of Letters Patent No. 633,160, dated September 19, 1899.

Application filed October 26,' 1897. ASerial No. 656.429. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW V. RYDER, a citizen of the United States, residing at Scio, in the county of I-Iarrison and State of Ohio, have invented certain new and useful Improvements in Wheeled Cultivators,of which the following is a speciiication, reference being had therein to the accompanying draw` ings.

This invention Vrelates to certain new and useful improvements in wheeled cultivators.

One of the objects of my invention is to vprovide means for throwing the weight of the frame forward of the wheel-spindles in order to keep the cultivatorproperlybalanced when the cultivator -beams are raised from the ground to keep the pole from tipping up and lifting against the horses necks.

Other objects of the invention are to improve the construction of cultivatorsI in the respects hereinafterpointed out and particu larly set forth in the claims.

My invention also has reference to details of construction and arrangement hereinafter appearing and particularly pointed out in the claims.

In the accompanying drawings, on which like reference-letters indicate corresponding parts, Figure `1 is a' plan view of a cultivator embodying my improvements; Fig. 2, a side elevation of the same with one of the Wheels removed, showing the cultivator-beams in cultivating position; Fig. 3, a similar view to Fig. 2, showing the cultiVator-beams in their raised or up position and wholly out of coutact with the ground; Fig. 4, a detail perspective view ot' one of the adjustable arched axle'su'pports and showing the means for holding the axle within said support and a portion of the connecting-bar for connecting the supports, and Fig. 5 adetail view of the compensating mechanism and diagramshowing its operation.

In illustrating my improvements I have shown them connected to au old form of cultivator, in which the letter A represents a suitable frame andthe letter B a pole attached thereto. This frame is supported by arched axles C, .having spindles D,upon which are fitted wheels Ein the usual manner. Ordinary cultivator-bearns, as shown at F, are pivoted to a bar Gr, which bar is adjustable up and down in the frame structure, whereby the cultivator-shovels H, carried by the cultivatorbeams, may be adjusted to run deeper or shallower, as desired.

Near the rear end of the cultivator-beams is pivotally attached a standard I by means of a bolt J passing through the standard and cultivator beam. To the upper end of this standard is secured a band or casting K, hinged toasuspension-armL,havingbranches at its lowerend, as seen at M, which branches are rigidly secured in any suitable manner to a rock-arm N, carried in brackets O, extending from asleeve P.

To the rock-arm at Q is attached what I term my compensating7 mechanism. This 'consists of a bar S, at one end of which is attached a chain T, preferably asprocket-chain, which passes around a sprocket-wheel U, carried by a bracket V, secured to the frame of the machine, and has its other end attached to a spring` W and which is also connected to the bar S. The spring YV may be tightened or loosened, according to which hole its links W are engaged with. It will be observed that the sprocket-wheel U is so mounted that it turns in an eccentric path when partially rotated, as it will be by the tension of the spring when the bar S moves from the fullline position to the dotted position shown in Fig. 5, as is the case when the cnltivator-beams are raised from thel ground. Thus this eccentric lifting sprocket-wheel is in effect an eccentric .take-up for the spring. Thus all slack in the chain due'to such movement of the bar S is taken up by the eccentric takeup and the tension remains nearly uniform, which is a valuable feature in coltivatorbeam-operating mechanism. When the cultivator-beams are in their lowered position and the plows are cultivating the soil, the raising effect of the spring W is nil or neutral, as the pull is directly through the deadcenter, so to speakthat is, the pivotal point of the eccentric take-up, the point Q where the bar S connects with the rock-arm N, and the pivotal point of said rock-arm are all in lineV when the shovels are in the ground, and the pull being along the line connecting these three points no effect is produced on the cultivatorbeams. The instant, however, the operator raises the cultivator-beams by taking hold of the handles o the point Q' is raised above theline of pulland the spring is at once effective.

Near the upper end of the suspension-arm L,

IOO

l have placed a sheave or pulley Y, over which passes a suitable lifting-ehain Z and secured to the standard I by hooking over any one of the teeth a, carried by the standard. The other end of this chain is attached to a spring Z', which in turn is attached to a rock-arm Z1, secured to a rock-shaft c by means of a setscrew d or otherwise, as desired. This spring assists in raising the cultivator-beams. To the other end of the rock-arm Z) is attached a rod or bar c, which connects with the castings f, secured to the wheel-spindles, but which allow the wheel-spindles D to be partially rotated. This is done by means of a suitable lever mechanism attached to the rock-shaft e and which consists of a lever P, a detent P carried thereby, and a toothed-segment P", with which saiddetent engages. lVhen the detent is released from engagement with the toothed segment, the lever may be thrown forward or backward, by which opei'ation the rock-shaft is partially rotated and the lower end of the rock-arm thrown backward or forward, as desired, and through the rod e throws the wheel-spindles back of the bearing-boxes P, presently to be described, in order to bring the weight of the frame forward of the wheelspindles when the cultivator-beams are in their raised position or out of the ground, as shown in Fig. 3. This more equally balances the cultivator when out of cultivating position and prevents the pole from lifting up on the horses necks. The upper end of the rockarm Z) when the beam is raised is thrown forward and takes up any slack on the chain Z, and hence the action of the spring Z' is not lessened when the beams are raised.

Referring now to the means for spreading the wheels apart more or less and at the saine time allowing the arched axles to partially rotate, it will be seen that I provide a suitable bearing-box P, into which the upper portion] of the arched axle is slipped. In this bearing-box a slot or pocketj is formed, into which a ring or collar k, provided with a suitable set-screw l, is placed. rlhe axle is slipped through this collar 7s, and when in the desired position the set-screw is tightened upon it and prevents its withdrawal from the collar, which comes in contact with the shoulders forming the sides of the slot or pocketj and holds the axle within the bearing. Then it is desired to spread the wheels, the set-screws l are loosened and the axle is shifted or slid outward or inward to the desired position, when the set-screw is then tightened and the axle is held in such adjusted position. Two of these bearings are used in the cultivator illustrated, one for each arched axle, and are secured to the frame structure by means of bolts m and n.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Iatent, is-

l. Iuawhecled cultivator, a suitable frame,

wheel-spindles connected therewith, a cultivator-beam pivotally connected to the frame, and means acting to both lift the beam and change the position of the frame relative to said wheel-spindles whereby the weight of the frame is thrown forward of the spindles when the beam is up.

2. In a wheeled cultivator, the combination with a suitable frame, having wheel-spindles connected therewith, and a cultivator-beam, of a rock-shaft carried by said frame, means connecting said beam and rock-shaft, and means for operating said rock-shaft to lift the beam and change the position of the frame relatively to the wheel-spindles, whereby the principal weight of the frame is thrown forward of the wheel-spindles, substantially as shown and described.

3. In a wheeled eultivator, the combination with a suitable frame having wheel-spindles connected therewith, and a cultivator-beam, of a rock-shaft carried by said frame, means connecting said rock-shaft and beam, a rockarm carried by said shaft, a connecting-rod connecting one of said wheel-spindles with said rock-arm, and means for operating said rock-arm, whereby the relative position of said frame and said wheel-spindles will be changed and the beam lifted, substantially as shown and described.

4. In a wheeled cultivator, the combination with a suit-able frame having wheel-spindles connected therewith, and a cnltiVator-beam, of a rock-shaft carried by said frame, a lever engaging with said shaft and adapted to rock the same, and suitable mechanism for oonnecting said rock-shaft and one of the wheelspindles and cultivator-beam, whereby when the rock-shaft is operated by said lever, the position of the wheelspindles will be changed and the beam lifted.

5. In a wheeled cultivator, the combination of a frame, a cultivator-beam pivotally supported near the forward end of said frame, a suspension-bar pivotally mounted on the frame near the rear thereof, a connection between said suspension-bar and said cultivatorbeam, a compensating yielding lifting mechanism between said suspension-bar and the frame, wheels for the cultivator, a bent axle for the wheels hinged to said frame, a rock-shaft, a lever for operating the same, a connection between an arm on said shaft and said bent axle, and a fiexible connection between an arm on said rockshaft and said connection between the suspension-arm and the beam and slidably supported by said suspension-arin, substantially as described.

In testimony whereof I allix my signature in presence of two witnesses.
